Fire monitor protective glass

Fire monitoring protection glass sapphire window piece

Uncoated sapphire has excellent surface hardness and a transmittance range from ultraviolet to mid-infrared wavelength region. Sapphires can only be scratched by a few other substances. The uncoated substrate is chemically inert and insoluble in water, common acids or bases at temperatures up to about 1000°C.

Sapphire has high temperature resistance, good thermal conductivity, high hardness, ultraviolet and infrared penetration, and good chemical stability. It is widely used in many fields of industry, national defense and scientific research (such as high-temperature resistant infrared window, etc.).
